Is magnesium hydrogencarbonate commonly found in lab?

In summary, the conversation discusses the question of what substances are commonly found in a laboratory to prepare magnesium sulphate by reacting with dilute sulphuric acid. The model answer lists four substances: Mg, Mg(OH)2, MgO, and MgCO3, with some additional clarification on how Mg(HCO3)2 reacts with H2SO4. The individual asking the question also provides an answer, including Mg(HCO3)2, and asks for confirmation on its validity. The conversation then shifts to discussing the stability of magnesium bicarbonate, with the individual providing evidence that it is stable enough to be sold in a lab setting.

Homework Statement


Hi,there is a question from my textbook:
Name FOUR substances commonly found in the laboratory to prepare magnesium sulphate by reacting with dilute sulphuric acid.


Homework Equations





The Attempt at a Solution


Here is my answer:
Mg(OH)2,MgO,MgCO3,Mg(HCO3)2
Here is the model answer:
Mg,Mg(OH)2,MgO,MgCO3

Mg(HCO3)2 react with H2SO4 to give MgSO4:
Mg(HCO3)2 (aq) + H2SO4 (aq) --> MgSO4 (aq) + CO2(g) + H2O(l)

Is it possible for me to write Mg(HCO3)2?If not,please explain briefly.
THX a lot.

Hi :smile:

Our lab has it, and I don't think its uncommon at all.

Can you show me a bottle of your magnesium bicarbonate? I was under the impression it was fairly unstable.

Apparenbtly it is stable enough to be offered for sale, google for its CAS number 2090-64-4.
